Located in Prince William Forest Park.

Oak Ridge Campground is a 100-site, wooded campground located in Prince William Forest Park, 35 miles southwest of Washington, DC. The park's land was set aside during the Great Depression, and in 1935 the Civilian Conservation Corps CCC began restoring the previously over-farmed acreage, converting it to recreational lands for public use. The CCC built trails, dams and cabins, making the park a wonderful place for recreation and relaxation. Large group camping is not permitted at Oak Ridge Campground.
